Dxgi.error NVidia 600 Issues
Ok so looks like we need to do this all over again. So if you are getting this error you most likely have nvidia's 600-series. Sometimes you get this even with cards from earlier series from nvidia.
So far funcom hasn't been able to fix this major issue. This issue isn't fixed by getting some other version of drivers you now have. Sure IF funcom works this out with nvidia some day they might be able to fix this with driver update but so far we are still waiting on funcom to work on this problem. As for now they have had countless reports from us players and they haven't been able to figure out what is causing this. Or so they said months ago as they were last heard of. So let's report everything here and make enough noise so they would fix this nasty issue some day.
Only fix for this issue that is proven to work is to make your Prefs_3.xml read-only. This will not help with the issue that the game would crash any less but at least you don't need to set your settings every time the game crashes because this issue. Note that you can't save any settings from game if the file is read-only so you can make changes for the session only.
The file can be found on a win7 machine from:
Users\<login name>\AppData\Local\Funcom\Conan\Prefs\
So keep reports coming and hopefully they will get to the bottom of this and fix it.
Nvidia 600 series cards. Possible solution!
I made a new character when I returned to the game 5 months ago. Since the day I arrived in Connels Valley with my new character I started crashing. I crashed a LOT. At times I would crash 2-3 times in 10 minutes.
I then discovered that if I use DX9 I would get a black screen for a few seconds instead of a crash and then the game would recover and go on.
I have now found a new solution!
I have added Age Of Conan to my list of games in Nvidia Control Panel->Manage 3D settings->Program settings. At the bottom of the list there is an option for Vertical Sync. I changed this to "Adaptive."
I have done this before the weekend and over the weekend I have raided heavily and solo'd a lot constantly running from one zone to another. This was with DX9 and all my setting to high and I had not 1 crash or black screen !!
Today I started feeling cocky and switched to DX10 with full settings and again I had no crashes or black screens at all. One thing I did notice was that sometimes there would be a brief stutter lasting 1 second but I'll take it over what was happening before.
The default setting is "Use the 3D application setting" so maybe if Funcom change the AoC default setting to "Adaptive" no one would have this problem anymore.
Please if you have been having problems like mine and this solution fixes things for you post here and let us know.
